8/1 Silva update

Carlos Silva was pulled from Sunday’s game in the first inning because of illness and was being evaluated by the Cubs. Silva faced four batters and threw 15 pitches, eight for strikes. Dexter Fowler flew out to center to start the Rockies’ first and Silva then walked Jonathan Herrera. Cubs pitching coach Larry Rothschild and assistant athletic trainer Ed Halbur went to the mound to check on the right-hander, but he stayed in the game.

Carlos Gonzalez then singled and Troy Tulowitski hit a ground-rule RBI double, and catcher Geovany Soto signaled to the Cubs’ dugout. Rothschild and head athletic trainer Mark O’Neal then went to the mound and Silva was pulled.

It’s the third time in his last four starts that Silva has failed to pitch beyond the second inning. He went 1 1/3 innings on July 11 against the Dodgers before he was ejected for arguing a close play at first base. He was pulled after giving up five runs on seven hits in one inning against the Astros on July 19.
